Seaway 7, a subsidiary of Oslo-listed Subsea 7, is the preferred bidder for a “very large contract” worth up to $750 million for ScottishPower Renewables’ East Anglia THREE offshore wind project in the UK.

Seaway 7 has signed a letter of exclusivity, and is finalising a preferred bidder supply chain agreement, with ScottishPower Renewables for this offshore wind project.

The contractor’s workscope would include the transportation and installation of 95 monopile foundations, associated seabed preparation and scour protection along with the engineering, supply and installation of the inner-array cables.

The workscope’s execution would be led from the contractor’s Aberdeen office and is expected to begin this year with the offshore workscope scheduled for 2024, subject to ScottishPower Renewables taking the final investment decision on the offshore wind project.

Three consented developments

East Anglia THREE is located about 70 kilometres offshore in the southern North Sea and is one of the three consented offshore wind farm developments that form the East Anglia Hub, planned by ScottishPower Renewables.

East Anglia THREE will contribute about 1.4 gigawatts of a potential 3 GW of renewable energy generation capacity at the East Anglia Hub.

We are pleased to support ScottishPower Renewables to progress the East Anglia THREE project,” Seaway 7 chief executive Stuart Fitzgerald said.

“Seaway 7 is looking forward to bringing over 10 years of offshore wind experience to one of the world’s largest offshore wind complexes, representing a significant contribution to the UK’s renewable target.”

Subsea 7 and Seaway 7 define a very large contract as being between $500 million and $750 million.
